According to The Sun, there are plans to stage a festival at London's O2 arena next summer. Girls Aloud are tipped to appear alongside acts including Coldplay and a possible performance from The Rolling Stones.

The fivesome are said to have instructed Shaw to find them an event on the same scale as Glastonbury to perform at.

"The girls are getting very excited," a source told the paper. "The promoters are only looking to book massive, show-stopping acts, which they would be perfect for.

"They would tick the pop box while The Rolling Stones would appeal to a much wider audience."
